Description
The XC9404 series are LED lighting offline controllers that use PFM(Pulse Frequency Modulation) control and have a Power Factor improvement function. The operating input voltage range is 85VAC to 270VAC, and the current is controlled on the primary side without using a Opto-coupler or secondary side control circuit. Because LED current fluctuations caused by input voltage fluctuations and LED voltage fluctuations can be suppressed, a stable LED lighting power supply is obtained.
Features
- Operating Voltage: 85VAC ~ 270VAC
- Output Wattage: up to 50W
- Power Factor / THD: Power Factor 0.95 or more / THD up to 10% attainable
- Harmonics regulations: IEC61000-3-2 class C compliance possible
- Control Method: PFM Control
- Function: Opto-coupler free due to primary control, Built-in acceleration Start, Low Start up Current 20μA
- Protection Function: LED Open/Short protection, Over Voltage Protection, Over Current Protection, UVLO
- Package: SOP-8D
- Operation Ambient Temperature: 40℃ ~ +105℃
Typical applications
- LED Lighting
